        // 4 局部内部类

        }
        like = new Like3();
        like.lambda();


        // 5.匿名内部类 没有类的名称 必须借助接口或者父类
        like = new ILike() {
            @Override
            public void lambda() {
                System.out.println("I like lambda4");
            }
        };
        like.lambda();
        // 6. 用lambda 简化
        like = () -> {
            System.out.println("I like lambda5");
        };
        like.lambda();
    };


        };


// 1. 定义一个接口
interface ILike{
    void lambda();

}
// 实现类
class Like implements ILike{
    @Override
    public void lambda() {
        System.out.println("I like lambda");
    }
}
